DAVID METZ, OF POTTSVILLE, PENNSYLVANIA.

IMPROVEMENT IN PUMP-VALVES.

Specification forming part of Letters Patent No. 123,922, dated February20, 1872.

To all whom it may concern:

Be it known that I, DAVID MEIZ, of Pottsville, in the county ofSchuylkill and in the State of Pennsylvania, have invented certain newand useful Improvements in Pump-Valve and do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawing andto the letters of referencemarked thereon making a part of this specification.

My present invention is intended as an improvement upon the pump-valvefor which Letters Patent were granted to me August 1, 1871; and itconsists in wrapping the interior metal rings or stays, whether one ormore, with a textile fabric saturated with a composition of beef-tallowand pine-tar, or their equivalents, before being driven into the shellof the pump-valve, so as to prevent, as much as possible, the water fromcoming in contact with the metal of which the rings or stays arecomposed, and to protect the rings or stays from the friction of thewater.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation,referring to the annexed drawing, in which-Figure 1 is a longitudinal vertical section, and Fig. 2 a horizontalsection of my pumpvalve.

A represents the shell, B the valve, and O O the rings or stays on theinterior of said shell, all constructed substantially in the samemanner, as described in my patent above referred to. In that case thewater came in contact with the metal of which the rings or stays O 0were made, which is obviated by my present invention.

' I make a composition of one-fourth beef-tallow and three-fourthspine-tar. The pine-tar is to be boiled down nearly to the consistency ofpitch and the tallow added while the tar is still hot, stirring it well,so as to make as perfect a mixture as possible. Some textile fabric orcloth is then saturated with said composition and wrapped around therings or stays O O, which are afterward driven into the shell A of thepump-valve. In the drawing this wrapping is marked a, By this means thewater is prevented from coming in contact with the metal rings or stays,which are thereby protected from the friction of the water.

I do not wish to be understood as specially claiming under this patent acomposition of beef-tallow and pine-tar by itself.-

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

The shell A, provided with one or more interior rings or stays O,wrapped with cloth or other textile fabric saturated with a compositionof beef-tallow and pine-tar, or their equivalents, substantially as andfor the purposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this30th day of December, 1871.
